The method of brewing coffee determines the taste of the final product as well as the type of coffee that can be used in the coffee machine. However, with commercial coffee machines, there are two other factors that are important to consider: the size and the operating speed. It is critical to get these variables right in order to be able to provide plenty of fresh, hot coffee to customers.The Size of the Coffee Machine

When choosing a coffee machine for a restaurant or catering business, it is essential that the machine has the capacity to serve enough people before another batch of coffee must be brewed. For instance, if there are 50 guests and 30 of them drink coffee, one should be able, in theory, to serve them all at the same time.The Operating Speed

The speed with which a machine makes coffee is also an essential determining factor in a purchasing decision. When the coffee runs out, whether the next batch is going to be ready in one or five minutes can make a huge difference to one's customers. Buying the fastest model you can afford is usualy a wise investment.
